To all '1o/10m, it 'may emmer/a.'

Be it known that I, FERDINAND llinainn, a citizen of the United States,and a resident of Plainfield, in the county of Union and State of NewJersey, have invented a new and Improved Intern:il-Combustion Motor, ofwhich the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in internalcombustion motors. y

It is one of the primary objects of the invention to provide a powercylinder to which a combustible charge and a charge of air are suppliedunder pressure.

It is a further object of the invention 'to construct the motor in sucha manner that the combustible charge will be supplied to the powercylinder iist andvsubseqnently 4placed under compression at which timethe air under compression is supplied to the power cylinder.

lt is a still further object of the invention to construct the motor insuch a manner that the foregoing operations are carried outautomatically. l

lVith thc above and other objects in view, reference is had to theaccompanying drawings, in which The ligure is a vertical Sectional Viewof a motor constructed in accordance wit-l1 the present invention, theview heilig taken at right angles to the crank shafts of the motor.

Referring more particularly to the drawings, the reference numeral 5designates the lower section of a two-part motor crank case, thereference numeral 6 designating the other section thereof. Thesesections 5 and 6 are secured together by means of bolts 7 to form thecon'lplete crank case.

Mounted in the crank case there are two cranks 8 and 9, and connected tothe cranks 8 there is a connecting rod l0, a connecting rod ll heiligconnected to the crank 9.

' Mounted upon the crank 8 Ithere is a gear wheel 12, and mounted uponthe crank 9 there is a gear wheel 13, such gear wheels 12 and 13 havingintermeshing engagement with each other. The connectingrod 10 ispivotally connected at its upper end, as at 14, to the piston 15, andsuch piston is mounted in a cylinder 16 which constitutes the powercylinder of the motor. This cylinder has an exhaust port 17 as shown.

The upper end of the connecting rod 11 is pivotally connected, as at 18,to the piston 19, working in a cylinder 20, and such cylinder 29 has acylinder 21 preferably of smaller diameter carried by its upper portion.The cylinder 20 is provided with an air intake 22, and ai discharge port23,

which discharge port is controlled by a check valve 24. Connected to thepiston 19 and extending upwardly therefrom, there is a tubular member25, the upper end 26 of which is open, the tubular member beingprovidedwith a port 27 near its lower end, and passing through a chamber28 formed in the upper cylinder.

Mounted in the upper cylinder 21 there is a' piston 29, and such pistonhas a skirt portlon depending therefrom. The piston 29 1s connected.with the piston 19 by the tubular member 25 heretofore mentioned. Theskirt portion 30 of the piston 29 is provided with two ports 3l and 32and such ports are adapted to alternately coincide with a passageway 33leading to the cylinder 16. On one side of the cylinder 21, there isformed an elongated chamber 34, and mounted in said chamber there is apiston 35, to the upper end of which is connected a rod 36, which inturn is pivotally connected, as at 37, to an angularly projecting arm 38of a rod 39. This rod 39 is connected 1n any desired manner to thetubular member 25 so that as the'pistons 19 and 29 reciprocate, thepiston will be caused to reciprocate therewith.

Leading from the lower end of the cham ber 34 heretofore mentioned thereis a pipe 40. This pipe 40 has communication with the chamber 34 and iscontrolled by a check valve 41. The opposite end of the pipe isconnected as at 42, to the cylinder 20, and leads into and hascommunication with the chamber 28 heretofore mentioned. Leading into thechamber 34 intermediate of its ends, there is a pipe 43, which has4communication with said chamber, and the passage of the pipe 43 iscontrolled by a check valve 44. The pipe 43 constitutes an inlet forlubricating oil, and the pipe 40 is the means by which this oil isdischarged into the chamber 28. To lubricate the tubular member 25 andthe piston 19 leading into the chamber 34 above the pipe 43, there is aipe 45, the passage of which is controlled ly a check valve 46, and thispipe 45 constitutes a gas inlet by means of which gas is admitted to thechamber 34. The chamber 84 has communication with the cylinder 21 bymeans of ports 47 and 48, which are in register with each other as shownin the drawings.

The device operates in the following manner:

It will be noted that the two cranks 8 and 9 are positioned nearlyopposite to each other in such a manner that as the piston 15 movesupwardly the pistons 19, 29 and 35 will movey downwardly, and viceversa. lVith the parts in the position shown in the drawings, the'piston15 has placed a charge of air under compression and a charge ofcombustible fuel under compression is being admitted to the cylinder 16in the compression space thereof. As the crank 8 passes over top deadcenter, the charge is ignited and the piston 15 is forced downwardly. Asthe piston 15 is forced downwardly, the pistons 19, 29 and 35 moreupwardly. The piston 19 in this movement places a charge of air undercompression in the cylinder 20 and the piston places the combustiblefuel in the chamber 34 under compression.

vWhen the crank 9 reaches top dead center and the crank 8 isapproximately at lower dead center, the air placed under compression inthe cylinder 2O will rush through the port 23 to fill the cylinder 1G.Simultaneously with this operation the combustible fuel in the chamber34 will, through the medium of the ports 47 and 48, pass into thecylinder 21. Immediately the piston 35 draws oil. into the lower portionof the chamber 34 through the pipe 43 and check valve 44. As the piston15 moves upwardly to place the air under compression which was deliveredto the cylinder 16 by the piston 19, the pistons 19, 29 and 35 descend.This operation places the combustible charge in the cylinder 21 undercompression and as the port 31 in the skirt 30 of the piston 29registers with the passage 33 in the cylinder 16, this charge ofcombustible gas under pressure rushes into the cylinder 16.

From the foregoing it is apparent that the above described operation isautomatically carried out so long as the motor is in operation, andthat, through the medium of the mechanism em loyed, the power cylinderof the motor 1s supplied with air and gas under pressure, the gas beingintroduced into the cylinder after the air therein-has been placed undercompression.
